AUTOMATIC CIGARQTIPCUTTER.

SPECIFICATION forming part of Letters Patent No. 567,277, datedSeptember 8, 1896. Application filed January 27, 1896. Serial No.577,037. (No model.)

driving mechanism to automatically cut off.

cigar-tips.

Another object is to provide suitable tripping and stop mechanism forthe same.

The features of our invention will be more fully set forth in thedescription of the accompanying drawings, forming a part of thisspecification, in which- Figure 1 is a central vertical section throughthe cigar-tip cutter and operative mechanism;

located therein. Fig. 2 is a side elevation of the operative mechanismand its supportingframe. Fig. 3 is a top plan view of the same. Fig. 4:is a perspective view of the wheel carrying the cutter-knives. Fig. 5 isan enlarged central vertical section through the same. Fig. 6 is abottom plan view of the plate and lugs against which the stop mechanismengages.

A represents the cutter-wheel armed with one or more knives a andjournaled by means of a shaft B in a frame 0.

D represents a shaft likewise journaled in frame 0 and carrying aspur-gear E, which engages and drives a spur-gear F on the shaft 13, inorder to rotate the cutter-wheel.

G represents a spiral spring, one end of which is looped over the studg, while the other end is secured to shaft D.

d represents a wrench or key seat by means of which shaft D is turned towind up the spring.

H represents the tripping-boss, which seats in a recess in thecutter-wheel and is held in position by means of a spiral spring h,seating in a socket at its inner end.

I represents cross-arms extending from opposite sides of boss H andseating in slots 1 cut in the opposite faces of the cutter-wheel. Therear end of the knife is cut out in a semicircle around the boss H, andits rearwardly-projecting arms form bridges across the slots "5 to limitthe outward movement of the boss II and cross-arms I.

J represents lugs or stops projecting downwardly from the under face ofplate K, upon opposite sides of the cutter-wheel, and against which thecross-arms I strike or engage to stop. the rotation of the cutter-wheel.

The operative parts are secured in the case in the following manner: Thetop plate L is secured to the plate K by means of screws passing throughlugs Z. The shell M is secured to the frame 0 by means of screws passingthrough lugs m.

Mode of operation: The spring G being wound up by means of a key onshank cl, the cross-arms I engage with the lugs J and prevent the springunwinding. When it is desired to cut off a cigar-tip, the tip is pressedupon the head of boss I-I through the opening N. As the cigar-tip ispressed against the boss II the boss yields, compressing the spring hand carrying arms I downwardly until they are free of the lugs J, whenthe wheel A revolves rapidly, bringing the knife around to cut off thatpart of the cigar-tip projecting through the opening N, after which thearms I, which follow the knife, engage with lugs J and stop the wheelwith the boss H, closing the opening N, after which it may again bereleased in the same manner.

e have shown two knives and sets of tripping mechanism upon thecutter-wheel, but a less or greater number may be employed if desired.

a represents grooves cut in the face of the cutter-wheel behind thebosses I-I, into which the cigar-tip projects as the cutter-wheelcommences to revolve. It will be observed that centrifugal force as wellas the spring It tends to hold the boss H inits outward position,causing it to act reliably and quickly, and the cross arms I,simultaneously engaging lugs upon opposite sides of the wheel, relieveit of any tendency to torsional strain which would occur if a stop wereused upon one side of the wheel only.

1. In a cigar-ti p cutter, the combination with a case having an openingfor. the insertion of the cigar-tip, of stop-lugs arranged upon theopposite sides of said opening, a

power-driven cutter-wheel journaled in fixed bearings and provided witha radial recess, said cutter-wheel being adapted to rotate beneath said0pening,a radially-movable springactuated tripping-boss seated in saidrecess, laterally-proj ecting arms on the opposite sides of saidtripping-boss operating to simultaneously engage the said stop-lugs, anda knife fixed on the cutter-Wheel in front of the tripping-boss andprovided with rearWardly-eX- tending arms projecting across the saidrecess and operating to limit the outward movement of the tripping-boss,substantially as described.

2. In an automatic cigar-tip cutter, the combination with a case havingan opening for the admission of the cigar-tip, of stop-lugs
